Color TV: total variation methods for restoration of vector-valued images
نویسندگان
چکیده
We propose a new definition of the total variation (TV) norm for vector-valued functions that can be applied to restore color and other vector-valued images. The new TV norm has the desirable properties of 1) not penalizing discontinuities (edges) in the image, 2) being rotationally invariant in the image space, and 3) reducing to the usual TV norm in the scalar case. Some numerical experiments on denoising simple color images in red-green-blue (RGB) color space are presented.

متن کاملRestoration of Color Images by Vector Valued BV Functions and Variational Calculus
We analyze a variational problem for the recovery of vector valued functions and we compute its numerical solution. The data of the problem are a small set of complete samples of the vector valued function and a significant incomplete information where the former are missing. The incomplete information is assumed as the result of a distortion, with values in a lower dimensional manifold. For th...
متن کاملTV-L Optical Flow for Vector Valued Images
The variational TV-L framework has become one of the most popular and successful approaches for calculating optical flow. One reason for the popularity is the very appealing properties of the two terms in the energy formulation of the problem, the robust L-norm of the data fidelity term combined with the total variation (TV) regularization that smoothes the flow, but preserve strong discontinui...
متن کاملTotal Variation Denoising and Enhancement of Color Images Based on the CB and HSV Color Models
Most denoising and enhancement methods for color images have been formulated on linear color models, namely, the channel-by-channel model and vectorial model. In this paper, we study the total variation (TV) restoration based on the two nonlinear (or nonflat) color models: the chromaticity–brightness model and hue–saturation– value model. These models are known to be closer to human perception....
متن کاملA Fast Algorithm for Vectorial Tv-based Image Restoration
In this paper, we firstly extend a simple algorithm proposed by Jia et al. [16] to color/vectorial images, and then apply it to some variational models for image restoration including color image denoising with the RGB and chromaticity-brightness(CB) color representation, chromaticity-brightness(CB) based colorization and inpainting etc. The variational models are all total variation(TV)-based ...
